Information for qualified electricians
5. Installation and electrical connection
DANGER
Electric shock in case of accidental contact with live parts. Electric
shocks may be fatal. Before working on the device, disconnect the
mains voltage and cover up live parts in the surroundings.
5.1. Installation of the device
Observe the admissible temperature range. Ensure sufficient cooling.
Snap the device onto a DIN EN 60715 mounting rail. The
connecting terminals must be at the top.
5.2. Connection of the device
Observe the admissible loads.
L
Do not connect three-phase AC motors to the actuator.
L
On delivery, the switching state is undefined.
Set the relays to the
OFF
position.
Connect as shown in the example (Fig. 2).
Fig. 2
Connect the bus with the bus terminal (Fig. 1, 3).
L
The connection to different phase conductors is possible.
L
For current detection, the device is equipped with contactless current
sensors. Magnetic fields in the immediate vicinity can result in false
current measurement results. If possible, lay feed and return line
closely side by side. Do not install devices producing magnetic fields in
the immediate vicinity of the actuator, e. g. doorbell transformer, power
contactor, etc.
